file_exists(path) is a shortcut for file_access(x, "exists");
dir_exists(path) and link_exists(path) are similar but also check that
the path is a directory or link, respectively. (file_exists(path) returns
TRUE if path exists and it is a directory.)
Usage
file_access(path, mode = "exists")
file_exists(path)
dir_exists(path)
link_exists(path)
Arguments
- path
A character vector of one or more paths.
- mode
A character vector containing one or more of 'exists', 'read',
'write', 'execute'.
Value
A logical vector, with names corresponding to the input path.
Details
Cross-compatibility warning: There is no executable bit on
Windows. Checking a file for mode 'execute' on Windows, e.g.
file_access(x, "execute") will always return TRUE.
Examples
file_access("/")
#> /
#> TRUE
file_access("/", "read")
#> /
#> TRUE
file_access("/", "write")
#> /
#> FALSE
file_exists("WOMBATS")
#> WOMBATS
#> FALSE
